Chelsea face stiff competition for Partizan Belgrade winger Lazar Markovic.

The exciting Serb talent has been a long-term target for Blues chief Michael Emenalo and emerging as a top target before the end of the season.

However, it's emerged Benfica have made a move for Markovic and are offering €15 million for the youngster.

Chelsea are understood to be willing to go to €20 million for the teen.
